Elcometer Ultrasonic Material Thickness Gauges (MTG) / Meters or Ultrasonic Thickness Gauges (UTG) are used to check the thickness of materials from one side only.

The thickness of materials cannot always be determined by direct measurement as access to both sides is not always possible. The effects of corrosion and erosion at the back of a metal panel may reduce its thickness significantly yet not affect the front surface. Pipelines, for example, may have been eroded by the flow of material inside. Machined or cast items may have thin walls that cannot be determined by callipers or other non-destructive tests.

The MTG range has the following instruments:

The Elcometer MTG2 Material Thickness Gauge with automatic transducer recognition which ensures correct probe identification even when the transducer is changed, a measurement rate of 4Hz (4 readings per second) and integral zero disc ensuring maximum accuracy of ±1%, makes the MTG2 ideal for taking basic thickness measurements.

The Elcometer MTG4 Ultrasonic Material Thickness Gauge with a choice of calibration options and measurement modes, the Elcometer MTG4 Ultrasonic Material Thickness Gauge is ideal for taking readings on a wide range of coated and uncoated materials.

The Elcometer MTG6 Ultrasonic Material Thickness Gauge with a choice of calibration options, measurement modes – including high speed scan mode, display options and data-logging. The Elcometer MTG6 Ultrasonic Material Thickness Gauge is ideal for taking readings on a wide range of coated and uncoated materials and downloading data for further analysis and reporting.

Finally, the Elcometer MTG8 Ultrasonic Material Thickness Gauge with a choice of calibration options, measurement modes – including high speed scan mode, display options and data-logging. The Elcometer MTG8 Ultrasonic Material Thickness Gauge is ideal for taking readings on a wide range of coated and uncoated materials and downloading data for further analysis and reporting.
